Be it knownthat I, JULIUs NEBERLE, a citizen of the United States,residing at Saginaw,

useful Improvements'in Holders for Sui-,- face-Indicating Gages; and Idoherebydeclare the following to be a full, clear, and

- having a exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and'use the same.

This invention relates to holders for surface indicating gages of thetype used for indicating inequalities of size or surface.

The object of the invention resides in the provision of a holder whichis adapted for use in operatively mounting various types of indicatinggages employed to center work and indicate variations in plain surfaces.

With the above and other objects in view, the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which Figure 1 is aside elevation of a portion of a milling machine showing the holdersupporting a Koch indicator, said indicator being utilized to properlylocate the drill of the machine in conjunction with the usual buttonemployed for such purposes, Fig. 2, a view partly in elevation, andpartly in section of the holder, showing same having a Brown and Sharpindicator associated therewith, Fig. 3, a view similar to Fig. 2 showingthe holder having a .St-arret indicator associated therewith, Fig. 4, aview similar to Fig. 2 showing the holder Koch indicator associatedtherewith, Fig. 5, a detail perspective view of a lengthening section tobe employed in the holder when necessary, Fig. 6, a detail perspectiveview of the knee section of the holder, Fig. 7 ,an enlarged section onthe line 77 of Fig. 2, Fig. 8, an enlarged section on the line 88 ofFig.

plurality of sections 10, 11 and 12 which are plvotally connected toeach other end to end. The section 10 is adapted to be se-, cured withinthe chuck A after the fashion of ordinary drill. The end of the section'10 which protrudes from the chuck A is forked so as to form arms 13 and1 1. The section 11 which constitutes the knee section of the holder hasits ends offset from each other and provided respectively withlongitudinally directed ears l5 and 16. These ears 15 and 16 areprovided with openings 17 and l 8'respectively, the opening'17 of thecar 15 being adapted to register with openings 19 formed in the arms 13and 14 of the section 10 when the ear 15 is inserted be tween said arms.When the opening 17 is disposed in registration with the openings 19 ascrew '20 is passed through the openings 17 and 19 and then engaged by athumb nut 21. In this manner the section 11 is pivot-ally connected tothe section 10 and may be readily moved to diflerent angular adjustmentsand then looked in a desired adjustment by manipulating the thumb nut21. The section 12 of the holder has its inner end forked so as to formarms 22 and 23 and these arms are provided respectively with alinedopenings 24:. In securing the section 12 to the section 11 the ear 16 ofthe sect-ion 11 is positioned between the arms 22 and 23 with theopening 18'of the ear 16 disposed in registration with the openings 24in the arms 22 and 23. A screw 24 is then passed through the registeringopenings 18 and 24 and a thumb nut 25 engaged with said screw. By thisconstruction it will be apparent'that the section 12 may be adjustedangularly with respect to the section 11 and locked in desired angularadjustments by manipulating the thumb nut 25 as will be apparent. Itwill be noted that the sections 10 and 12 are flattened as at 10 and 12on their outer faces at the points where they are adapted to be engagedby the thumb nuts 21 and 25 respectively when the latter are in lookingposition. This flattening of the sections 10 and 12 is resorted to forthe purpose of presenting a more extensive friction surface to the thumbnuts 21 and 25 and thereby increase the efi'ectiveness of the lockingact-ion of the latter.

The outer end of the section 12 is enlarged and provided with atransverse openmg 26. In securing a Koch indicator,

designated at K to the holder the securing stud 27 of such indicator isinserted through the opening 26 and the usual thumb nut 28 then engagedwith the threaded outer end of said stud. In securing a Starretindicator designated at S to the section 12 of time holder, there isemployed a clamping device indicated generally at C. This device isshown as comprising a shank 29 having a threaded portion30 at one endand an enlarged portion 31 at the other end provided with an opening 32therethrough. Slidable on the enlarged portion 31 is a sleeve33 providedwith openings 34 adapted to register simultaneously with the opening 32as said sleeve is moved longitudinally of the enlarged portion 31. Thisenlarged portion 31 is further provided with a groove 35 in itsperiphery in which is engaged a pin 36 fixed in the sleeve 33 andadapted to lock said sleeve against axial rotation on the enlargedportion 31 and also limit the longitudinal movement of said sleeve onsaid enlarged portion.

The shank 29 of the clamping device C is inserted in the opening 26 inthe section 12 and a thumb nut 37 then engaged with the threaded portion30 of said shank. The openings 34 of the sleeves 33 are then broughtinto registration with the opening 32 of the enlarged portion 31 and thesecuring stud 38 of the Starret indicatorsinserted through saidregistering openings. It will be noted that when the openings 34 of thesleeve 33 are in registration with the opening 32015 the enlargedportion 31 the inner end of said sleeve projects sli htly beyond theinner end of the enlarge portion 31 so that when the thumb nut 37 isscrewed on the end of shank 29 the sleeve 33 will be drawn intoengagement with the section 12 before said section is engaged by the Iinner end of the enlarged portion 31. This Sharp engagement of thesleeve 33 with the section 12 will tend to force the sleeve outwardly onthe enlarged portion and thus friction the walls of the openings 34against the securing stud 38 so as to lock the indicator S to theholder. In securin a Brown and indicator to the 1older the same clampingdevice C is utilized but instead of the securing stud of the indicatingdevice being inserted through the openings 32 and 34 a separate arm 39is inserted through said openings and the outer end of this armterminates in a forked portion including arms 40 and 41 having aliningopenings 42 therein respectively. The Brown I and Sharp indicator isdesignated at D and is shown provided with a securing ear 43 having anopening 44 therein. This ear 43 ,is inserted between the arms 40 and 41so as to bring the opening 44 into registration with the openings 42. Ascrew 45-is then passed through the registering openings 44 v and 42 anda thumb nut 46 engaged with the threaded end of the screw. Bymampulating this thumb nut 46 it will be apparent that the indicator Dwill be clamped between the arms 40 and 41 and said indicator therebysecured to the holder.

It will be noted that by roviding the knee section 11 with offset en sthe various indicators, when assembled with the holder is disposed onthe same side of section 12 as section 10.

. In some instances it is necessary to lengthen the holder and to reachthis end there is provided a lengthening section 47 one end of which isprovided with an ear 48 adapted to be inserted and pivotally securedbetween the arms 13 and 14 of the section 10 by the screw 20 and thumbnut 21, while the other end of said lengthening section is forked toform arms 49'and 5'0 adapted to receive the car 17 of the section 11between them, said sections 11 and47 being pivotally secured together bymeans of a screw 51 and thumb nut 52 as will be obvious. understood thatas many lengthening sections may be utilized in the holder as theparticular circumstances demand.

What is claimed is:

1. A holder for indicating gages comprising a plurality of sectionspivotally connected to each other end to end. for independent swingingmovement, means for locking said sections -in difierent angularadjustments with respect'to each other, one of the terminal sectionsbeing'adapted for insertion in a chuck and the intermediate sectionhaving its ends ofiset from each It will be other whereby the terminalsections will be disposed on opposite sides of the longitudinal centerof the intermediate section and the longitudinal axes of said terminalsections disposed parallel, and means carried by the last named terminalsect-ions for securing an indicator thereto with its longitudinal axisdisposed in a common vertical lane with the longitudinal axis of thefirst named terminal member.

2. A holder for indicating gages comprising a plurality of sectionsnected to. each other end to end for independent swinging movement,means locking said sections in different angular adjustments withrespect to each other, one of the terminal sections of said holder beingadapted for insertion-in a chuck, means carried by the other terminalsections for securing anindicator thereto in longitudinal alinement withthe first named terminal section, said means comprising serted through atransverse opening in the.

last named terminal section and having one end threaded and its otherend provided with an enlarged head havin opening theret rough, a thumnut engaged on the threaded end of the shank whereby pivotally confor ashank m-- a transverse the manipulation of sanie will draw the enlargedhead toward the last named terminal section,

a sleeve slidable on the enlarged head and provided with alined openings5 adapted head, the inner end of said sleeve being disposed beyond theinner end of the head when the openings of the sleeve and head are 10sleeve against axial and thro ugh the openings of the head and sleeve toregister with the opening in theand adapted to be locked againstdisengagement therefrom by frictional contact wlth the walls of theopenings in the sleeve when 15 the latter is drawn against the lastnamed terminal section by the manipulation of said thumb nut.
